Introducing the Kestrel Drop D3 Wireless Temperature, Humidity And Pressure Data Logger – Red. A compact and robust device designed to monitor a comprehensive range of environmental conditions. It accurately measures temperature, humidity, heat index, dew point temperature, barometric pressure, density altitude, and pressure trends, making it ideal for diverse applications such as manufacturing, agriculture, healthcare, transportation, and recreational use. With its small dimensions of just 1 x 1.8 x 2.4 inches and a weight of only 1.2 ounces, the DROP D3 is easy to position and can be used almost anywhere, ensuring reliable monitoring where you need it most.
Built to withstand extreme conditions, the Kestrel DROP D3 meets military and international standards for durability, boasting a rugged design that is waterproof to IP67 standards and compliant with MIL-STD-810G for shock resistance. It is equipped with a sturdy D-ring, allowing users to hang the device in various settings for continuous environmental monitoring. The device delivers real-time data logging capabilities through the Kestrel LiNK app, which connects wirelessly via Bluetooth at a range of up to 100 feet. Users can view live readings, manage multiple DROP loggers simultaneously, and easily share data via email or social media.
The Kestrel DROP D3 provides precise measurements, such as a temperature accuracy of +/- 0.9F and a relative humidity accuracy of +/-2% RH, accommodating a wide range of conditions. Additionally, it boasts a substantial data logging capacity, allowing for the storage of over 6,000 data points with settable intervals ranging from every 2 seconds to 12 hours. Powered by a user-replaceable CR2032 battery, the DROP D3 is designed for long-term usage, making it an invaluable tool for professionals and hobbyists alike who require accurate environmental monitoring in real-time or logged data format.
